Question

I am new to java and am trying to build the logic to run a chess game. I have a superclass called ‘Piece’ and subclasses for king, knight, queen etc. I am trying to implement a move method where I determine the type of piece on the fly and then call that piece’s corresponding move method. For example:

int typeOfPiece = _board[startX][startY]._theKind;
Piece myPiece;

switch(typeOfPiece)
{
    case 1:
        myPiece = new Pawn(startX, startY, team);
    case 2: 
        myPiece = new Rook(startX, startY, team);
    case 3:
        myPiece = new Knight(startX, startY, team);
}

boolean myPiece.canMove(endX, endY);

Is there a way that I can ensure the canMove method will be called by the correct type of piece in this example?

Thanks

Override canMove in all subclasses and make it abstract in the parent class Piece.
